Constructor & Destructor Documentation

Curve (  int  segs = 30, int  order = 4 )

Default constructor. Sets the the subdivision of the curve into 30 segments, and sets the order of the curve to 4 (for a cubic curve).

Member Function Documentation

void AddControlPoint (  const Vec &  p  )  [inline]

Adds a new control point to the curve.

void Clear (   )  [inline]

Clears all control points from the curve.

int GetNumControlPoints (   )  const [inline]

Returns the number of control points in the curve.

int GetNumSegments (   )  const [inline]

Returns the number of segments the curve will be subdivided into when being rendered.

int GetOrder (   )  const [inline]

Returns the order of the spline.

virtual void Render (   )  [virtual]

Draws the shape. Implements Shape.

void SetNumSegments (  int  segs  )  [inline]

Sets the number of segments in which to subdivide the curve. The default is 30.

void SetOrder (  int  order  )

Sets the order of the spline. The order of the curve is its degree + 1. The order is clamped to the range [0, GL_MAX_EVAL_ORDER].
